I got to shoot the P320 model line at a Sig sponsored event last spring. Really liked it (classic Sig 5 point safety system and slide cycle striker pre-load), the compact model with the large grip installed was on the small side for my taste. I only got to shoot the 9mm at that time, but there was talk of the P320 being available in 357Sig (think 9mm on steroids) and 45acp sometime in the future.

Really hard to make a bad choice in the entire Sig Sauer model line, if you feel comfortable with the controls, and are able to handle the recoil of selected caliber, no "bad choices" exist. Sigs are pricey, but you get a weapon that any knowledgeable/Sig control familiar gun owner would carry into the worst combat situations. If I get access to another Sig event, and the 357Sig & 45acp P320 is available, I will attend.

Got to Elm Fork with the Sig P227 & Walther PPQ 45acp, 300 rounds and a sore wrist later, the Walther will be my new CC weapon (once purchased).

The Walther has less felt recoil (polymer frame absorbing some force?) but SLIGHTLY more muzzle flip (lighter/less mass vs P227). These two guns share a near identical bore axis, so that's not it

EVERY striker fire gun manufacturer need to use the PPQ trigger as a benchmark for trigger design, it's that good. Found I was faster/more comfortable with the PPQ at 2 round center mass twice (two silhouette targets, 20 ft distance/4 ft apart). That I've done the draw/double tap double target drill a few 100 times with the P227, and it was FIRST TIME with a PPQ had me scratching my head! The PPQs more intuitive trigger and lower mass (less time from holster to first shot) more then made up for the added muzzle flip.

Make no mistake, the Sig would be my gun of choice to taking into a combat zone for an extended period of time, but I like the Walther for everyday CC/self defense better.
